CPYBWP

If I have a structure like the following:

DCL  SPCPTR     .Query_Data_Offset; 
DCL  DD          Query_Data_Offset 
                 BIN(4) 
                 BAS(.Query_Data_Offset); 

if I then have an instruction like

CPYBWP  .Query_Data, .QuerySpc;

shouldn't it be

CPYBWP  Query_Data, .QuerySpc; 

or are they both the same?  When using a CPYBWP using two pointers, does 
it merely change the .Query_Data pointer to point to QuerySpc?  If not is 
it possible that this may overwrite some other memory location?  Thanks 
for the help.




Bobby.
